Specific embodiment

Below, in conjunction with accompanying drawing and specific embodiment, this utility model is described further:

The splitter of dust cap as shown in Figure 1, including volume adjusting apparatus 1, puncture core 2, connector 4, valve element 5, bullet Property part 6, trachea branch connect core 7 and securing member 8, volume adjusting apparatus 1 are snug fit at connection along the axis direction of valve element 5 Part 4, puncture core 2, valve element 5 are respectively positioned in connector 4；Puncture core 2 one end is connected to volume adjusting apparatus 1 upper end inner surface, separately One end is plugged in valve element 5；The sliding action of volume adjusting apparatus 1 drives puncture core 2 along the central axial direction shifting of valve element 5 Dynamic；Elastic component 6 is fixed in valve element 5 one end away from puncture core 2；It is tee T that trachea branch connects core 7, and this tee T is wherein One port is used as the installing hole 9 with the cooperation of connector 4 screw thread；Valve element 5 and elastic component 6 are movably arranged in described installing hole 9, Securing member 8 is removably fixed in trachea branch and connects core 7 two ends.

Trachea branch is accessed on the supply main sebific duct (not shown) of polisher and connects core 7, securing member 8 is passed through at its two ends Fastening, prevents main pipeline gas leakage, elastic component 6 and valve element 5 is pressed in installing hole 9 successively, elastic component 6 is in compression shape State, is easy to the ejection of valve element 5, is convenient for changing, keeps in repair；The lower end of connector 4 is bolted in trachea branch and connects on core 7, and air quantity is adjusted Puncture core 2 is secured firmly in connector 4 regulating device 1.

When needing to be passed through gas in dust cap it is only necessary to volume adjusting apparatus 1 glide along the axis direction of valve element 5, Puncture core 2 is pushed, is against on valve element 5 and extends to the inside of it, puncture core 2 forms path with connecting in valve element 5, can will be responsible for Gas in road is drawn to be passed through in dust cap and is used；Deficiency in draught, when can not meet job demand, continue downslide air quantity and adjust dress Put 1, puncture core 2 is continued to push, increase the space connecting with valve element 5, increase ventilation；Air quantity is excessive, impact job demand When, volume adjusting apparatus 1 are moved along along the axis direction of valve element 5, reduces the space connecting with valve element 5, reduce ventilation.When When not needing to be passed through gas in dust cap, volume adjusting apparatus 1 are moved along along the axis direction of valve element 5, no longer to puncture core 2 There is provided the pressure pushing, the impact of compressed gas, puncture core 2 is disconnected with valve element 5, no longer draw the gas in main pipeline.

Further, volume adjusting apparatus 1 are attaching nut, and connector 4 outer surface is provided with thread groove 10, attaching nut with Connector 4 threaded one end coordinates.Volume adjusting apparatus 1 slide and turn for screw thread along the axis direction of valve element 5 with respect to connector 4 Dynamic slide, rotate attaching nut and be capable of attaching nut threadingly groove 10 slides, thus regulating air volume or closing, opening Open air supply channel convenient, this outer connector 4, attaching nut are coordinated by screw thread, connect even closer.

Further, all install rubber seal 3 additional between puncture core 2, valve element 5 and connector 4, the valve of elastic component 6 is installed Rubber seal 3 is installed additional between core 5 end and installing hole 9.Install rubber seal 3 additional to be prevented from drawing letting out of gas from main pipeline Dew is so as to connect even closer, good sealing effect.

Further, elastic component 6 is spring, can provide enough elastic force to valve element 5, is easy to the ejection of valve element 5, conveniently more Change, keep in repair.

Further, the surface at trachea branch connection core 7 two ends offers thread groove 10 or serrated slot.

Further, securing member 8 is locking nut or strip iron plate, corresponds to the table that trachea branch connects core 7 two ends respectively Thread groove 10 or serrated slot that face opens up.

As shown in Fig. 2 when the surface that trachea branch connects core 7 two ends opens up thread groove 10, securing member 8 is locking screw Mother, trachea branch is connected core 7 and is firmly accessed in main pipeline by locking nut.As shown in figure 3, when trachea branch connects 7 liang of core When the surface at end opens up serrated slot, securing member 8 is strip iron plate, and trachea branch is connected core 7 and bundled by strip iron plate, firmly connects Enter in main pipeline.

Further, as shown in figure 4, securing member 8 is glue pipe socket, the surface that corresponding trachea branch connects core 7 two ends opens up Serrated slot, first glue pipe socket is enclosed within the main sebific duct of supply, then corresponding trachea branch is connected core 7 two ends and packs into the main glue of supply In pipe, finally using press device, glue pipe socket is tightly pressed against on the main sebific duct of supply, prevents trachea branch from connecting the leakage of core 7 two ends Gas, is suitable for high, medium pressure supply main sebific duct use.

Further, trachea branch connection core 7 one end connecting supervisor removably arranges filter.Filter energy Enough filter the impurity such as the rust powder of doping, greasy dirt, moisture in gas, clean gas breathing environment is provided, reduce occupation disease as far as possible Generation.

It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim Within the scope of.
